I am studying the role of PNK in biochemical processes. I understand it has some important functions, but I'm not sure exactly what they are. Could someone explain the function of PNK to me?

    These enzymes are capable of adding phosphate groups to nucleic acid molecules, thereby modifying their structure.

    Polynucleotide kinases (PNK) represent a class of DNA modification enzymes with distinct functions.

    This means they can catalyze the removal of phosphate groups from nucleic acids, demonstrating their versatility in DNA modification.

    The process involves transferring the gamma phosphate group from adenosine triphosphate (ATP) to specific sites on the DNA or RNA.

    Specifically, PNK targets the 5' hydroxyl termini of these nucleic acids for phosphorylation.
